Hi folks,
 
I'm finally ready to tighten up the turn buckles on the rudder and elevator cables on my CH 701.
 
If I remember right, Caleb or Roger told me they use 18 # on the elevator with the ubiquitous bungee cord on the top cable.
 
So I don't have to re-invent the wheel where did you folks put the bungee cable - and one person said he used a spring system.  All your thoughts please.  I'm old, big and fat and the less time I have to crawl around in the Hell Hole the better
 
I can't remember what was said about the rudder cables for tension.
 
Do the cables stay in proper tension after the first flight or two - or do you have to repeat the process???
 
I'm building from a kit... is all this written in the plans somewhere????.  I can't find it!!!
 
Need your thoughts on both cables and why what you did worked for you.

In practice, I fitted the bungee across to the RHS fuse and ahead of the crossover to the top elevator cable that comes off the control horn, so this is the lower elevator cable. Reason for this is to keep the control stick biased to neutral using the bungee tension to counter the assymetric tension of the elevator cables with respect to aileron position.

You will find out what I mean when you do it.
